ALBERT C. MELTON, OF SEDALIA, MISSOURI.

LAWN-IVIOWER.I

To all whom t may concern,.-

Be it known that I, ALBERT O. MELTON, a citizen of the United States,residing at Sedalia, in the county of Pettis and State of Missouri, haveinvented certain new and useful Improvements in Lawn-Mowers, of whichthe following is a specification.

My invention relates to lawn-mowers of the reciprocating-cutter-b artype, and has for its object the improvement of machines of that type,consisting in simplifying the construction thereof and providing anefficient and simple means for transmitting power to the cutter-bar.

The construction of my invention will be described in detailhereinafter, and illustrated inthe accompanying drawings, in which-Figure 1 is a front view of my improved lawn-mower Fig. 2, a side viewpartly in section Fig. 3, a detail view of the power-transmittingmechanism; Fig. 4, a detail view of one of the supporting-casters Fig.5, a detail view of one of the side plates.

In the drawings similar reference characters indicate correspondingparts throughout the several views.

My improved lawn-mower has a plate lat each side thereof, each of saidplates having a stud-shaft 2 thereon, on which are journaled thedrive-wheels 3 and a pin 4, to which is secured the handle 5, 6indicating other` pins on said plates, against which the ends of thehandle bear to enable the operator to lift the front of the machine. Thecutter-bar 7 is of the reciprocating type and is mounted near the frontends of plates 1.

8 indicates the drive-shaft, journaled in plates 1 and having spur gearpinions 9 eyed to the ends thereof to mesh with a gearface l() on theinner side of the rim of drivewheels 3. The middle of shaft 8 is formedwith an obliquely arranged crank 11, on which is j ournaled an arm 12,having a pin 13 slidably mounted therein with a ball 14,

15 indicates two blocks secured to cutterbar 7 and having their abuttingportions formed with hemispherical depressions 16 and comprising asocket in which the ball 14 is seated.

It will be understood that as the shaft 8 ro- Speccation of LettersPatent.

tates the free end of arm 12 is reciprocated, thus imparting areciprocating motion to the cutter-bar 7.

17 indicates rollers j ournaled on short shafts 18, formed integral withserrated and slotted uprights 1'9 and adjustably secured to the frontend of each plate l to regulate the height of the cutter-bar from theground.

Having thus described my invention, what I claim is 1. In a lawn-mower,a rotary shaft, an obliquely-arranged crank formed in said shaft, an armjournaled on said crank, a pin slidably mounted in said arm, a ball onthe end .of said pin, a reciprocating cutter-bar, and a socket on saidcutter-bar to receive said ball, substantially as shown and described.

2. In a lawn-mower, plates having studshafts thereon, thesupporting-wheels journaled on said shafts, a shaft journaled in saidplates having an oblique crank therein intermediate of its` ends,operative connections between said shaft and the supportingwheels, areciprocating cutter-bar'having a socket thereon, an arm journaled onsaid oblique crank, and a in slidably mounted in said arm having a balon its outer end mounted in the socket aforesaid, substantially asshown and described.

3. In a lawn-mower, plates having studshafts thereon, thesupporting-Wheels journaled on said shafts having internal gearfaces, ashaft journaled in said plates, gearpinions keyed to the ends of saidshaft and meshing with said internal gears, an obli ue on said crank, apin slidably mounted in said arm and having a ball on its outer end, areciprocating cutter-bar mounted between said plates, and a socket onsaid cutter-bar to receive the ball on the end of the pin, substantiallyas shown and described.

4. In a lawn-mower, plates having studshafts thereon, thesupporting-wheels journaled on said shafts having internal gearfaces, ashaft journaled on said plates, gearpinions keyed to the ends of saidshaft and meshing with said internal gears, an obli ue crank formed insaid shaft, an arm journa ed on said crank, a pin slidably mounted insaid crank formed in said shaft, an arm journa ed- Ioo i arm, a ball onthe end of said pin, a reeiprol rollers journaled on said stud-shafts,substancating cutter-bar mounted between said tially as shown anddescribed. plates, a socket on said bar to receive said A C MELTON all7pins on said plate, the handle secured to 5 said pins, serrated uprightsadjustably se- Witnesses: l
